Continuous by Categorical Interaction in Linear Regression (SPSS Tutorial Video #27)

Описание: In this video, I explain how to conduct a continuous by categorical interaction in linear regression using SPSS. There are seven steps demonstrates:

1. Coding a categorical variable appropriately (dummy coding)
2. Centering a continuous variable
3. Computing an interaction term
4. Running the regression itself
5. Checking model assumptions like (heteroskedasticity)
6. Interpreting the model coefficients
7. Plotting the results.

This SPSS tutorial series is designed to teach you the basics of how to analyze and interpret the results of data using SPSS. I will cover everything from the very basics of the main windows within SPSS, to manipulating data, to running and interpreting meaningful analyses like t-tests, ANOVA, regression, and many more, and visualizing results.
